Is it possible to disable the interlocutor's video in BlueJeans Prime for iOS?

I use BlueJeans Prime for videoconference on iOS 11 (iPad). When in a videoconference, is it possible to disable the interlocutor's video?

The motivation is to reduce the network usage.


For BlueJeans (not Prime), one can swipe up, which will activate the "low bandwidth" mode:

Swipe down to go back to the normal mode.

That doesn't work for BlueJeans Prime.


BlueJeans' tech support told me it is not possible. They don't have any plan to support the option in the future.
